geometry nodes LOD(3.0+)

LODs(Level Of Detail) node group for instancing up to 4 models with different levels of details to optimize far away objects. instead of instancing high poly model across large distances you can set higher poly objects close to the camera and lower poly objects far away.

instructions:

1. Download the ".blend" file.

2. Append the node group "LOD instancing HN V2_5 {append this}" and or "LOD instancing advanced HN V2_5 {append this}" (or 2_6 if using 3.1 and above)

3. Plug the different levels of geometry details to "Geometry Distance" 1 - 4 (you don't have to use all the sluts)

4. Plug the output sockets to "Instance on Point" node

parameters:

inputs:

"Camera" select the active camera.

"Level (1 - 4) Geometry" plug the different levels of details when "1" is the most detailed(closest to the camera) and "4" is the least detailed(farthest from the camera). in order, you don't have to use all the sluts(for example: do not plug to input 1,2,4).

"Use Last Geo Behind Camera" replace all the objects behind the camera to the last level of details(lowest poly).

"Min Distance" the minimum distance of the first level of detail.

"Max Distance" the distance of the transition to the last level of detail.

"Pick Instance" allow you to pick instance by index or any other integer(if not more then 1 instance is connected the value will have no impact).

"Randomize Instance" randomize the index which result a randomize of the instances of the collections & instances in the same level.

"Seed" change the seed of the "Randomize Instance" option.

advanced:

all the settings are the same as the standard except the option in advanced to change every control individually per level

outputs:

"Instances" the combined instances joined to a single geometry output. plug to the "Instance" input of the "Instance on Point" node.

"Behind The Camera Selection" selection of all the area in front of the camera in order to instance only in this area(optional). plug to the "Selection" input of the "Instance on Point" node.

"Instance Index" the index of every instance set by the node's parameters. plug to the "Instance Index" input of the "Instance on Point" node and enable "Pick Instance".
